hi there!
I have a problem with my audio konfiguration. on kde startup I get sounds but as example in vlc,wine and firefox(flash on youtube) I get nothing.
I never had more than one soundcard in my system but with the hdmi device I think I need some extra configuration.

can you please tell me how I should get this done...the strange thing is I get some sound on kde but not at the rest of the system.

some more information about your environment would be useful.
Do you use pulseaudio or not, do you still use your normal soundcard for anything (are speakers connected), what graphics driver do you use, ...
Since your setup seems to work in principal I guess you just have to configure your .alsarc correctly.
